Astronaut's Serious Medical Event Cuts ISS Mission Short

Crew-11's mission to the International Space Station (ISS) concluded early on January 15, 2026, following a serious medical episode experienced by astronaut Mike Fincke. NASA determined that an early, coordinated return was the safest course of action, allowing Fincke access to superior medical imaging capabilities unavailable in orbit. This event marks the first instance of an ISS mission being shortened due to a crew member's health.

During the mission, a portable ultrasound machine, a standard piece of equipment on the ISS since 2011, proved instrumental in diagnosing Fincke's condition. Astronauts utilize ultrasound for monitoring cardiac and eye health, crucial in microgravity where fluid shifts can pose risks like blood clots and vision impairment. Fincke is currently undergoing reconditioning at NASA's Johnson Space Center.
